Draw guide and procedure for the realisation and for the assembly thereof

ABSTRACT

The quick assembly draw guide comprises a shaped body which has a device for connection to the wall of the draw.  
     This comprises a first member for the attachment to the wall and means for deforming a portion of the surface for the displacement of the first attachment member along a direction perpendicular to the axis of the body up to a position substantially coinciding with the thickness of the wall.  
     The procedure for the realisation and assembly of the guide consists of shearing a slot and at the same time two opposite tabs leaving a staple between the tabs and said slot, of shearing a point facing the staple on the vertical side of the guide, of deforming the slot to displace said tabs simultaneously along a direction perpendicular to the axis of the guide up to a position substantially coinciding with the thickness of the wall, of associating the wall with the guide, of bending the tabs by 90° and of applying a pressure on the tabs and the point against the wall to anchor them to it.

[0001] The present invention refers to a draw guide and to a procedure for the realisation and assembly thereof.

[0002] As is known draw guides comprise a body which has a lower side, which is connected to the base of the side walls of the draw, having a transversal extension which is greater than the thickness of the aforementioned side walls of the draw.

[0003] The guide also comprises hooks which are connected to the side wall of the draw.

[0004] Such a traditional draw guide has some drawbacks, mainly due to the fact that, since the lower side of the guide has a transversal extension which is greater than the thickness of the walls of the draw, a substantial amount of material is consumed and there is a substantial amount of swarf.

[0005] The technical task proposed by the present invention is, therefore, that of realising a draw guide and a procedure for the realisation and assembly thereof, which allow the aforementioned drawbacks of the prior art to be eliminated.

[0006] In this technical task a purpose of the invention is that of realising a draw guide and a procedure for the realisation and assembly thereof which allow the material consumption to be substantially reduced with respect to that which is necessary in the prior art.

[0007] Another purpose of the invention is that of realising a guide and a procedure which allow the realisation of very strong hooking tabs which guarantee an excellent attachment of the guide to the draw, since the strong section of the tabs is defined by the width of the tabs themselves and not by the thickness of the material.

[0008] The last but not least purpose of the invention is that of realising a guide and a procedure which allow the realisation of tabs which are very strong, since they are not subjected to multiple deformations which can cause the weakening thereof.

[0009] The technical task, as well as these and other purposes, according to the present invention, are achieved by realising a quick-assembly draw guide comprising a shaped body with, on a support surface of a wall of the side of a draw, a connection device for attaching said body to said wall, characterised in that said connection device comprises at least one first member for attaching to said wall and means for deforming a portion of said surface for the displacement of said first attachment member along a direction perpendicular to the axis of said body up to a position substantially coinciding with the thickness of said wall.

[0010] Advantageously, the present finding also refers to a procedure for the realisation and assembly of a draw guide, characterised in that it consists of shearing a slot on the surface of the guide suitable for supporting a wall of the side of the draw and at the same time two opposite tabs leaving a staple between said tabs and said slot, of shearing a point facing said staple on the vertical side of the guide, of deforming said slot to displace said tabs simultaneously along a direction perpendicular to the axis of said guide up to a position substantially coinciding with the thickness of said wall, of associating said wall with said guide, of bending said tabs by 90° and of applying a pressure on said tabs and said point against said wall to anchor them to it.

[0011] Other characteristics of the present invention are defined, moreover, in the subsequent claims.

[0012] Further characteristics and advantages of the invention shall become clearer from the description of a preferred but not exclusive embodiment of the draw guide and the procedure for the realisation and assembly thereof according to the finding, where the guide is illustrated for indicating and not limiting purposes in the attached drawings, wherein:

[0013]FIG. 1 shows a plan view of a draw guide according to the finding associated with a draw (shown with a dotted and dashed line) before the tabs are bent;

[0014]FIG. 2 shows a plan view of a portion of the guide according to the finding which has not been deformed;

[0015]FIG. 3 shows a plan view of the portion of guide of FIG. 2 when it has been deformed;

[0016]FIG. 4 shows a plan view of the portion of guide of FIG. 3 associated with a draw shown with a dotted and dashed line, with the tabs and an attachment member folded;

[0017]FIG. 5 shows a section view carried out along the line V-V of FIG. 4; and

[0018]FIG. 6 shows a front view of the guide not applied to the draw.

[0019] With reference to the quoted figures, a draw guide is shown wholly indicated with the reference numeral 1.

[0020] The guide 1 is of the quick assembly type and comprises a shaped body 2 which has, on a support surface 3 of a wall 4 of the side of the draw, a connection device 5 for the attachment of the body 2 to such a wall 4.

[0021] The connection device 5 comprises at least one first member 6 for the attachment to the wall, and means 7 for deforming a portion of the surface 3, for the displacement of the first attachment member 6 along a direction perpendicular to the axis of the body 2 up to a position substantially coinciding with the thickness of the wall 4.

[0022] Advantageously, the maximum width of the surface 3 of the body 2 is less than the minimum thickness of the wall 4 of the draw.

[0023] The guide 1 comprises, moreover, a second attachment member 8 engaging with the wall 4 on the opposite side to the first member 6. As shown in the figures, the first attachment members 6 comprise a tab which extends on the same plane as the surface of the body 2 and which is equipped at its end with a hooking head 9.

[0024] In particular, the guide according to the finding comprises at least two tabs 6 which are identical and arranged facing one another. Advantageously, the tabs 6 have a bending line perpendicular to the axis of the body.

[0025] Moreover, the deformation means 7 comprise at least one slot which extends parallel to the axis of the body and which defines, on a portion of the surface 3 of the body, a staple 11 which supports the two tabs 6.

[0026] The slot 7 has widened zones 12 at its ends to ease the deformation of the portion of the surface 3 of the body and the displacement of the staple 11 and of the tabs 6 beyond the maximum width of the surface 3.

[0027] In a preferred embodiment, the second member 8 engages in the wall 4 in a zone which is equidistant from the tabs 6.

[0028] The present finding also refers to a procedure for the realisation and for the assembly of a draw guide.

[0029] The procedure consists of shearing the slot 7 on the surface 3 of the guide 1, suitable for supporting the wall 4 of the side of the draw and, at the same time, two opposite tabs 6, leaving a staple 11 between said tabs and the slot 7.

[0030] The procedure also consists of shearing a point 8 facing towards the staple 11 on the vertical side of the guide 1 and of deforming the slot 7 to displace the tabs 6 simultaneously along a direction perpendicular to the axis of the guide 1, up to a position substantially coinciding with the thickness of the wall 4.

[0031] The procedure also consists of associating the wall 4 with the guide 1, of bending the tabs 6 by 9° and of applying a pressure on the tabs 6 and on the point 8 against the wall 4 to anchor them to it.

[0032] Advantageously, the tabs 6 have their bending line perpendicular to the axis of the guide 1.

[0033] Moreover, the slot 7 has widened zones 12 at its ends to ease the deformation of the slot 7 and the displacement of the staple 11 and of the tabs 6 beyond the maximum width of the surface 3.

[0034] In practice it has been noted how the draw guide and the procedure for the realisation and the assembly thereof according to the invention are particularly advantageous because they allow material to be saved with respect to the prior art and the reduction of swarf.

[0035] In practice, therefore, the guides according to the finding are very cost-effective.

[0036] The draw guide and the procedure for the realisation and for the assembly thereof thus conceived are susceptible to numerous modifications and variants, all falling within the scope of the inventive concept; moreover, all of the details can be replaced with technically equivalent elements.

[0037] In practice, the materials used, as well as the sizes, can be whatever according to the requirements and the state of the art.
